Hello Hannez, welcome back. I seem to remember you from a long time back in the Lounge.
I don’t know a great deal about the Samsung Blu-ray drives. The one you have may be one of the last drives available that is still able to do scans, according to Ibex, Jadburner and others. As for burning, you will simply have to test yours to see some results. Jadburner doesn’t seem too impressed with the drive, and I’d certainly avoid burning at 2x with it and these discs.
I do not believe that BDR discs are inherently more reliable than recordable DVD’s. They will vary in consistency just as badly as the earlier optical media. I had some Ritek discs become completely unreadable in a period of 3 to 4 years. Obviously, I do not recommend Ritek at all. But I haven’t had any issues with Verbatim (with Verbatim mid codes) or FTI/Falcon discs, and many around here recommend Panasonic. The Panasonic discs are getting hard to find however, and I keep seeing rumors that they are leaving this business.
I do advise staying away from the LTH variety of Blu-ray recordable discs, as we still see reports that those are less compatible.
I haven’t seen any issues when storing discs in a spindle. But many people are reporting problems with Blu-ray discs when stored in wallets, (like these) especially when there is any pressure applied, like stacking them on top of one another.
I prefer individual cases for long term storage.
